Abstract

An airbag system includes an airbag, and the airbag includes an airbag body having a passenger-side wall portion that is arranged at a passenger side when having completed deploying and inflating, and a slip cloth that is disposed at an outer surface side of the passenger-side wall portion. The slip cloth formed in a loop shape an axial direction of which is in a left and right direction includes: a front panel portion arranged at a passenger side; an upper back panel portion extending downward from an upper end of the front panel portion; and a lower back panel portion extending upward from a lower end of the front panel portion, and a lower end of the upper back panel portion and an upper end of the lower back panel portion are mutually approximated, and joined to the passenger-side wall portion.

1. An airbag system including an airbag folded and stored and allowing an inflating gas ejected from an inflator to flow in so as to deploy and inflate,
 the airbag including an airbag body having a passenger-side wall portion that is arranged at a passenger side when having completed deploying and inflating, and a slip cloth that is disposed at an outer surface side of the passenger-side wall portion, 
 the slip cloth formed in a loop shape an axial direction of which is in a left and right direction and comprising: 
 a front panel portion arranged at a passenger side; 
 an upper back panel portion facing the passenger-side wall portion at a back side of the front panel portion, and extending downward from an upper end of the front panel portion; and 
 a lower back panel portion facing the passenger-side wall portion at the back side of the front panel portion and extending upward from a lower end of the front panel portion, 
 wherein a lower end of the upper back panel portion and an upper end of the lower back panel portion are mutually approximated and joined to the passenger-side wall portion, the lower end of the upper back panel portion and the upper end of the lower back panel portion being jointed together along a line located in a vicinity of a center of the passenger-side wall portion. 
 
     
     
       2. The airbag system according to  claim 1 , wherein respective width dimensions in the left and right direction of the front panel portion, the upper back panel portion, and the lower back panel portion are made substantially identical from an upper end to a lower end of the slip cloth, and
 the lower end of the upper back panel portion and the upper end of the lower back panel portion are joined to the passenger-side wall portion across substantially the entire area in the left and right direction. 
 
     
     
       3. The airbag system according to  claim 1 , wherein
 the slip cloth comprises: 
 a left back panel portion arranged on the passenger-side wall portion at a back side of the front panel portion and extending rightward from a left end of the front panel portion; and 
 a right back panel portion arranged on the passenger-side wall portion at a back side of the front panel portion and extending leftward from a right end of the front panel portion, and 
 a right end of the left back panel portion and a left end of the right back panel portion are mutually approximated, along with the lower end of the upper back panel portion and the upper end of the lower back panel portion, in the vicinity of a center of the back side of the front panel portion, and joined to the passenger-side wall portion. 
 
     
     
       4. The airbag system according to  claim 1 , wherein the lower end of the upper back panel portion and the upper end of the lower back panel portion are jointed together and to the passenger-side wall portion along the line by sewing.
